Getting DHTML right

In the hands of an inexperienced developer, DHTML can become a nightmare
for everyone who comes
into contact with it, and all too often it does. Visitors see the
most obvious effects, but maintenance and development suffer too.

In
Well-Behaved DHTML: A Case Study, Aaron Boodman uses an example DHTML script to show the main problems
that can come up when implementing it. He also lays out five basic steps for developing
DHTML scripts.

• Define the logical structure of the implementation
• Build a fully working example
• Identify the requirements of all user agents (UAs)
• Write code that translates the logical requirements into UA requirements
• Test on every target platform
